Most people know something about the greenhouse effect. Factories send gasses such as carbon dioxide, or CO₂, into the atmosphere, the air around the earth. In the past, this wasn’t a problem because trees absorbed the CO₂. But now people in many countries are cutting down billions of trees all around the world. At the same time, factories are sending more CO₂ into the atmosphere. It’s difficult to believe, but factories put billions of tons of CO₂ into the atmosphere every year. One ton is over 2000 pounds, so it is a lot of pollution. There is too much CO₂ and there aren’t enough trees, so the world is getting warmer. In other words, we have a greenhouse effect. This is terrible for the environment.
What can we do about this? Firsts we can stop using so much coal and oil. We can learn to use different kinds of energy:  the sun, wind, steam from volcanoes，and heat from inside the earth. Second, instead of cutting down trees, we should plant more trees. One tree can absorb ten pounds of carbon dioxide every year.
The trees are good for the earth’s atmosphere and for Guatemala (拉丁美洲国家危地马拉).In small towns and villages in Guatemala, most women are poor and have hard lives. Trees help them in three ways. First, the Connecticut factories pay them to plant the trees. Their pay is com, not money. The com is good for their children. Second, these women know a lot about their environment. They know where to plant when to plant, and what kinds of trees to plant. For example，they plant many fruit trees. The fruit gives them vitamins for their families^’ s diets. Other trees are good for firewood. In a few years, the women won’t spend so much time looking for firewood. Third, all these trees are good for the soil. Now rain can’t wash the soil down from the mountains so easily.
This plan isn’t enough to stop the greenhouse effect. However, it’s a start. The woman of Guatemala are helping themselves and helping their environment.
32. Which of the following statement is NOT true?
A. Factories send more CO₂ into the atmosphere.
B. Trees can’t absorb the same CO₂ as they did in the past.
C. Billions of trees are being cut down throughout the world.
D. The greenhouse effect is extremely bad for the environment.
33. What’s the main idea of the second paragraph?
A. The reasons why we should plant more trees.
B. Ways we can adopt to take heat from volcanoes.
C. Measures to be taken to forbid the use of coal and oil.
D. Things we can do to stop or reduce the greenhouse effect.
34. How does planting trees help improve women’s lives in Guatemala?
A. By preventing the greenhouse effect.
B. By developing their skills of planting trees.
C. By enabling them to earn more money to support their family.
D. By making them get com and fruit to feed their family in return.
35. What’s the author’s attitude towards the plan of planting trees in Guatemala?
A. Critical. B. Neutral.
C. Positive. D. Doubtful.
32. B   33. D    34. D    35. C
32. 细节理解题。由文中第一段的There is too much CO₂ and there aren’t enough trees, 可知，是因为树木越来越少，二氧化碳越来越多，所以才无法像以前一样能吸收掉，而不是因为树木的吸收力不如以前了，B选项表述错误。故B选项正确。
33. 主旨大意题。由第二段“Firsts we can stop using so much coal and oil. We can learn to use different kinds of energy:  the sun, wind, steam from volcanoes， and heat from inside the earth. Second, instead of cutting down trees, we should plant more trees. One tree can absorb ten pounds of carbon dioxide every year.”可知，首先，我们可以停止使用煤和石油。我们可以学习使用不同种类的能源：太阳、风、来自火山的蒸汽和来自地球内部的热量。第二，我们应该多种树，而不是砍树。一棵树每年可以吸收十磅二氧化碳。所以第二段主要讲了我们可以做些事情来阻止或减少温室效应。故D选项正确。
34. 细节理解题。由倒数第二段的First, the Connecticut factories pay them to plant the trees. Their pay is com, not money. For example，they plant many fruit trees. The fruit gives them vitamins for their families, diets. Other trees are good for firewood可知，首先，康涅狄格州的工厂付钱让他们植树。他们的工资是com而不是钱。例如，他们种植许多果树。水果为他们家庭的饮食提供了维生素。其他的树是很好的柴火。所以在危地马拉，获得的钱和水果来养活家人帮助改善了危地马拉女性的生活。D选项正确。
35. 推理判断题。根据文中倒数第二段的第一句The trees are good for the earth’s atmosphere and for Guatemala以及最后一段“This plan isn’t enough to stop the greenhouse effect. However, it’s a start. The woman of Guatemala are helping themselves and helping their environment.”可知，这些树对地球大气层和危地马拉都有好处。这个计划不足以阻止温室效应。然而，这只是一个开始。危地马拉的妇女正在帮助自己和环境。所以通过关键词“good，helping themselves and helping their environment.”可以判断出，作者对于在危地马拉种植树木的态度是积极，乐观的。故C选项正确。
